Trying to compile this code: 
#!perl
use strict;
use warnings;

use 5.020;

my @Org = (9, 1,0);

my $N= #Org;


say "N = $N";

say @Org;

[download]
But getting this error: Global symbol "$N" requires explicit package name (did you forget to declare "my $N"?) at code.pl line 12. syntax error at code.pl line 14, near "say" Execution of code.pl aborted due to compilation errors. What do I do wrong?

Sorry for a stupid question! But I want to learn: 've seen this kind of error many times in my programs -- probably I'm missing something very basic.

Thank you! :)
